Pet toilet

Abstract

A pet toilet 10 having a toilet box 13 , a drainboard 14 partitioning the toilet box into an upper compartment and a lower compartment, an excreta treating material 15 laid in the upper compartment, and an urine absorbent member 11 laid in the lower compartment. The drainboard is an integral structure formed of a plurality of longitudinally extending ribs 17 spaced parallel with each other and a plurality of transversely extending ribs 18 a and 18 b intersecting the longitudinally extending ribs 17 and spaced parallel with each other to have drain holes 12 . Each drain hole 12 has a longitudinal dimension S 2 at least twice its transverse dimension S. The transversely extending ribs include ribs 18 a with a smaller height H 1 from the drainboard surface 14 a downward and ribs 18 b with a larger height H 2 from the drainboard surface 14 a downward, the ribs 18 a and the ribs 18 b alternating with each other.

1 . A pet toilet comprising a toilet box, a drainboard partitioning the toilet box into an upper compartment and a lower compartment, an excreta treating material laid in the upper compartment, and an urine absorbent member laid in the lower compartment,
 the drainboard being integrally constructed of a plurality of longitudinally extending ribs spaced parallel with each other and a plurality of transversely extending ribs intersecting the longitudinally extending ribs and spaced parallel with each other to have drain holes,   each drain hole having a longitudinal dimension at least twice the transverse dimension thereof, and   the height of the rib with the least height of all the ribs measured from the surface of the drainboard downward being at least 0.8 times the transverse dimension of the drain hole.   
   
   
       2 . The pet toilet according to  claim 1 , wherein the height of the rib with the least height of all the ribs measured from the surface of the drainboard downward being at least 0.8 times the transverse dimension of the drain hole. 
   
   
       3 . The pet toilet according to either of  claims 1  or  2 , wherein the transverse dimension of the drain hole is 2 to 8 mm.
